The remap option generates new mappings for unmapped attribute columns or parameter arguments based on the metadata of the data source to which the mobile business object (MBO) is bound.
For MBOs that already have mappings, selecting Remap remaps parameters and attributes to the data source based on the new data source definition.
Customers[ID, Surname, GivenName, Address, Phone]As the developer, you want to eliminate the “Address” column and better represent the address information. You modify the database schema to:
Customers[ID, Surname, GivenName, Street, City, State, Country, PostalCode, Phone]The MBO attributes become out of date because of the schema change, requiring the developer to Refresh the metadata. After you refresh, the "Address" attribute is unbound. Without remap, you would manually add attributes and map them to the columns in the tabular view. Selecting Remap creates the new attributes and maps them to the appropriate columns automatically based on the modified metadata.
